Hello again, I have a little problem with my Audi S2 Coupé and since the search had not helped me I try my luck now here. Today wanted to drive down the window of the driver’s door and it did nothing. Passenger door, rear display window as well as the sliding roof went. So I dismantled the door panel and measured through. Electricity was on the switch and on the plug connection to the engine at the push of a button. Also the switch lit. Furthermore I have a switch changed to exclude a defect of the switch. I noticed that the engine was very warm. So I thought a little bit wait and test again later. 2 hours later he ran up and down a few times. Moment waited and again did nothing. A few weeks ago I also had it on the driver’s side nothing moved. But then went again and was all good. Until today. What is that supposed to be? Motor came from the previous owner not too long ago. eu in, since the train was torn. Can it be as described in the search a cold soldering point in the ECU? Only then not everything should fail and the lighting also failure? Thank you for your help!!
